The value of the hidden variables needs to exactly match the reporting value of the answer option in the checkbox question.

For example, if your checkbox question has answer options of apple, orange, and banana – the hidden variable would need to say ‘apple’ in order for apple to be selected in the checkbox (via the default answer field). This article could be a good reference:

You could reference the Hidden Value (via merge code) in the default answer field. Keep in mind that the checkbox question would need to be on a page after the Hidden Value. Also, because you are wanting to select multiple options in the checkbox, these will need to be comma separated.

So in your Default Answer field in the checkbox question, this should probably look something like this:

[question(“value”), id=”1″],[question(“value”), id=”2″] (these are just example merge codes but should be separated by a comma and no spaces.
